Abstract: An implantable medical device having a sensing module and a control module is configured to receive a cardiac electrical signal and sense events from the cardiac electrical signal received via electrodes carried by a medical electrical lead when the medical electrical lead is coupled to the implantable medical device. The control module coupled is configured to detect non-sustained tachyarrhythmia (NST) episodes based on sensed event intervals and determine if the sensed event intervals during the detected NST episode satisfy oversensing criteria. If the oversensing criteria are satisfied, the control module determines whether the detected NST episode satisfies non-lead related oversensing criteria and withholds a lead integrity alert when the NST episode meeting the oversensing criteria is determined to satisfy non-lead related oversensing criteria.

Abstract: A medical device coupled to extracardiac electrodes is configured to analyze a cardiac electrical signal over a signal analysis segment to determine if shockable rhythm classification criteria are met, determine that TWOS detection criteria are met for the signal analysis segment when a predetermined number of TWOS analysis windows are classified as TWOS, and classify the signal analysis segment as non-shockable in response to determining that the TWOS detection criteria are met.

Abstract: A medical device is configured to deliver a shock to a patient's heart via electrodes coupled to the medical device and set an escape interval timer to start running an escape interval after delivering the electrical shock. A sensing module of the medical device is configured to sense a cardiac event in response to a cardiac electrical signal received by the medical device crossing a sensing threshold. The medical device determines if the cardiac event meets reset criteria and allows the escape interval timer to continue running the escape interval if the cardiac event does not meet the reset criteria.
